Embodiment 1

[0024] Because existing rounding machines cannot guarantee bending accuracy and require manual support of the bending section, a rounding machine for aluminum profiles with auxiliary support was designed. The specific solution is as follows:

[0025] like Figures 1-4 As shown, a rounding machine for processing aluminum profiles includes: a machine base 1, a roller group, and an auxiliary support wheel. The roller group is located at the front of the machine base 1 and includes multiple sets of conveying rollers 3 and a set of bending rollers. The conveying rollers 3 are connected to a conveying motor 301 to control the rotation of the conveying rollers 3. The bending roller includes a fixed wheel 4 and a movable wheel 5. The fixed wheel 4 is located above the movable wheel 5. The movable wheel 5 moves and adjusts along an arc-shaped trajectory with the fixed wheel 4 as the center, so that the movable wheel 5 contacts the aluminum profile and bends it. The auxiliary support wheel is equipped with a position acquisition component, which can acquire the position of the bent aluminum profile and adjust the position of the support wheel so that the support wheel fits the surface of the aluminum profile, eliminating the shape deviation caused by material springback and improving accuracy.

[0026] like Figure 1 As shown, in this embodiment, the front side of the machine base 1 is the working area, and the roller group and auxiliary support wheels are both located in the working area. The roller group is located on the right side of the machine base 1 and includes three sets of conveying rollers 3 and one set of bending rollers. The surfaces of the conveying rollers 3 and the bending rollers are made of plastic to avoid contact with the surface of the aluminum profile and damage to the aluminum profile. The set of bending rollers is located on the left side of the roller group. The aluminum profile is fed from the right side and conveyed to the left by the rotation of the conveying rollers 3. A control console 101 is provided on the top of the machine base 1 or the front side of the support 2. The control console 101 is used to set the bending parameters of the aluminum profile and can obtain the bending status of the aluminum profile in real time to facilitate equipment adjustment. A sensor 6 is provided on the right side of the conveying rollers 3 to sense whether an aluminum profile is being placed. In order to ensure the straight conveying of the aluminum profile, an annular groove can also be opened on the surface of the conveying rollers 3 to match the cross-sectional shape of the aluminum profile. After the aluminum profile is placed, it can limit the aluminum profile and make it conveyed in a straight line to avoid deviation.

[0027] like Figure 1 , 2 As shown, the auxiliary support wheel includes a horizontal support wheel 7 and a vertical support wheel 8. The horizontal support wheel 7 is located above the vertical support wheel 8. Both the horizontal support wheel 7 and the vertical support wheel 8 have small rollers at their front ends to ensure smooth movement of the aluminum profile. In this embodiment, the horizontal support wheel 7 includes a first horizontal wheel and a second horizontal wheel arranged opposite to each other. The first horizontal wheel and the second horizontal wheel are respectively connected to a set of lead screw motor assemblies for individual adjustment to adapt to different bending shapes.

[0028] like Figure 2As shown, both the horizontal support wheel 7 and the vertical support wheel 8 are connected to a screw motor assembly to adjust the position of the rollers. The screw motor assembly is located inside the machine base 1 and includes a slide table, an adjusting screw 802, and a servo motor 801. The slide table is slidably connected to the adjusting screw 802, and the servo motor 801 is drive-connected to the adjusting screw 802 to control the rotation of the adjusting screw 802. In this embodiment, the screw motor assembly of the horizontal support wheel 7 is located on the upper part of the machine base 1, and the screw motor assembly of the vertical support wheel 8 is located on the left side of the machine base 1. The horizontal support wheel 7 and the vertical support wheel 8 are arranged in a perpendicular relationship.

[0029] like Figure 1 , 2 As shown, the position acquisition component includes a bracket 2 and a vision camera 201. The vision camera 201 is mounted on the bracket 2 and located in front of the machine 1. The vision camera 201 is electrically connected to the control console 101. The image captured by the vision camera 201 is transmitted to the control console 101 for analysis and processing. In this embodiment, a pulley is provided on the bottom front side of the bracket 2 to facilitate the sliding of the bracket 2. The shooting range of the vision camera 201 is directly facing the upper left side of the machine 1.

[0030] The machine tool 1 is equipped with a sector gear 502 for mounting the movable wheel 5. The center of the sector gear 502 is connected to the fixed wheel 4. The machine tool 1 is also equipped with an adjustment motor 501. The output end of the adjustment motor 501 is connected to a drive gear 5011, and the drive gear 5011 meshes with the sector gear 502. The adjustment motor 501 controls the drive gear 5011 to rotate in both directions, which in turn causes the sector gear 502 to rotate clockwise or counterclockwise. The rotation of the sector gear 502 will drive the movable wheel 5 to move.

[0031] like Figure 3 As shown, a transmission chain 303 is provided between the conveying rollers 3 for transmission connection. Each conveying roller 3 has at least one connecting gear 302 at its rear for mounting and connecting the transmission chain 303. Specifically, the rotation of the conveying motor 301 drives one of the conveying rollers 3 to rotate, which in turn drives the other conveying rollers 3 on the same side to rotate, thereby realizing the conveying of aluminum profiles. In other schemes, a transmission gear is provided between the conveying rollers 3, which causes the conveying rollers 3 on the same side to rotate in the same direction.

[0032] Both the conveying roller 3 and the bending roller are installed with a quick-release structure at their front ends. The quick-release structure is a limit screw 304, which facilitates quick replacement of conveying roller 3 and bending roller of different sizes to meet the bending processing of aluminum profiles of different sizes. Each connecting gear 302 is connected to a rotating shaft. The conveying roller 3 and the bending roller are splined to the rotating shaft for quick assembly and disassembly.

[0033] like Figure 2As shown, the bracket 2 is slidably connected to the machine base 1. The sliding connection part is provided with a sliding screw and a sliding motor 11 to realize electric sliding. In this embodiment, the bottom sides of the bracket 2 are also provided with sliding rods 10 that are slidably connected to the lower part of the machine base 1. One end of the sliding screw is screwed to the bottom of the bracket 2, and the other end is connected to the sliding motor 11. The sliding motor 11 is a servo motor 801 to ensure that the bracket 2 can move precisely into place and ensure the setting distance of the vision camera 201 without frequent adjustments. The top of the bracket 2 and the top of the machine base 1 are also provided with a sliding rod 10 and an auxiliary sliding part 9 of a linear bearing to maintain smooth and stable sliding.

[0034] Working principle:

[0035] First, place one end of the aluminum profile between the conveying rollers 3. After the sensor 6 detects the aluminum profile, the conveying motor 301 starts and conveys the aluminum profile to the left. After conveying to the first bending position, the conveying stops. The conveying rollers 3 can also clamp and limit the aluminum profile. Then, the movable wheel 5 starts to move to bend the aluminum profile to the preset angle. When continuous bending is required, the movable wheel 5 keeps the working position still and the conveying wheel continues to convey, so that the aluminum profile can be bent smoothly.

[0036] After being bent, the aluminum profile continues to move to the left. Once it enters the range of the vision camera 201, the vision camera 201 can determine the correct bending shape of the aluminum profile. This allows the longitudinal support wheel 8 to be controlled to move upwards until it contacts the aluminum profile, maintaining its precise bending shape. As the aluminum profile continues to bend and moves upwards, the transverse support wheel 7 is adjusted to a suitable position to contact the aluminum profile and maintain its bending shape. The auxiliary support effect of the transverse support wheel 7 and the longitudinal support wheel 8 prevents the aluminum profile material from springing back, causing bending deviations and affecting processing accuracy.

[0037] The rounding machine in this solution is equipped with movable wheels 5 that can move along an arc-shaped trajectory to perform bending or rounding operations on aluminum profiles. During bending, the movable wheels 5 move along an arc, reducing the pressure on the aluminum profile and preventing easy deformation of the surface. An auxiliary support wheel is located on one side of the machine's discharge direction. During operation, a vision camera 201 identifies the current position of the bent aluminum profile and controls the lead screw motor to adjust the position of the auxiliary support wheel, providing auxiliary support to the aluminum profile and eliminating deviation caused by material springback. To improve bending accuracy, the visual camera 201 eliminates the need for manual support during bending operations, thereby increasing equipment efficiency. The visual camera 201 is equipped with a separate bracket 2. During normal operation, the distance between bracket 2 and machine base 1 is relatively small, making it difficult to inspect structural components. Therefore, bracket 2 is connected to an electrically controlled sliding component, allowing bracket 2 to move independently away from machine base 1, widening the distance between bracket 2 and machine base 1 for easier maintenance. Furthermore, the electrically controlled sliding component can precisely restore bracket 2 to its preset position, eliminating the need for recalibration of the visual camera 201. Example 2

[0038] In this embodiment, the structure of the rounding machine is basically the same as that of Embodiment 1. The difference is that pressure sensors are added to the horizontal support wheel 7 and the vertical support wheel 8 to monitor the contact pressure between the support wheel and the aluminum profile in real time. The automatic fine-tuning screw motor is controlled by closed loop to reduce visual feedback delay and further improve support accuracy and anti-springback efficiency.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
